But the 29 year-old, who will race arch-rival and defending Olympic 5,000m champion Kenenisa Bekele on the track in Eugene in America on Saturday, insisted: "I've got a big race coming up so I just wanted to do enough to win rather than set a record time. It’s going well, it’s all going in the right direction.
"I left my vest in the hotel and only realised when I got to the start of the course and tried to get it out of my bag for a picture. My agent had to nip back and get it."
Farah added: "I've had another year of running and I am feeling stronger now, compared to previous seasons.
"I am very excited about the Olympics. The crowd were going crazy cheering me on today, even the fun runners as they were jogging along."
Farah, who flew back to his training base in Oregon last night has also announced plans for a fund-raising ball just days after he hopes to be celebrating Olympic gold.
He set up the The Mo Farah Foundation with wife Tania to raise funds for famine victims in Africa after visiting Somalia — where he was born — last year.
